Description

Technical Field

[0001] This utility model belongs to the field of fan technology, and specifically relates to a fan head and a desktop fan. Background Technology

[0002] Fans are primarily used to provide airflow to regulate indoor temperature and increase air circulation. In existing technologies, the electrical connection between the fan's display screen and the main control module is typically quite simple, using a direct cable to connect them. This direct cable connection is susceptible to external vibrations and other factors, posing a high risk of cable damage and affecting the normal operation of the display screen. Furthermore, since the display screen, fixed to the fan cover, is directly connected to the main control module via cable, it is difficult for users to disassemble and clean the fan cover, reducing user experience and making maintenance inconvenient.

[0003] Therefore, it is necessary to provide a new technical solution to solve the above-mentioned technical problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is the inconvenience of maintenance and the poor user experience.

[0005] In a first aspect, this utility model provides a fan head; the fan head includes a fan body, a display screen, and an electrical connection mechanism. The fan body has an inlet side and an outlet side arranged opposite each other along a front-to-back direction. The fan body includes an inlet shroud on the inlet side, an outlet shroud on the outlet side, and a main frame located between and connected to the inlet and outlet shrouds. The outlet shroud is detachably connected to the main frame. The display screen is mounted on the side of the outlet shroud facing away from the inlet shroud. The electrical connection mechanism includes a first electrical connector electrically connected to the display screen and a second electrical connector electrically connected to a main control module. The first electrical connector is mounted on the outlet shroud, and the second electrical connector is mounted on the main frame. When the outlet shroud and the main frame are connected, the second electrical connector contacts the first electrical connector, allowing the display screen to be electrically connected to the main control module via the electrical connection mechanism. The display screen can display relevant data when electrically connected to the main control module.

[0006] Secondly, this utility model provides a desktop fan; the desktop fan includes a base, a support structure, the aforementioned fan head and a main control module, one end of the support structure is connected to the base, the air inlet shroud is connected to the other end of the support structure, and the main control module is disposed inside the base.

[0007] Based on the fan head and desktop fan provided by this utility model, the main frame is designed to be connected to the air inlet shroud and the air outlet shroud respectively. The main frame is located between the air inlet shroud and the air outlet shroud. The air inlet shroud is located on the air inlet side, and the air outlet shroud is located on the air outlet side. The display screen is installed on the side of the air outlet shroud away from the air inlet shroud. In the electrical connection mechanism, the first electrical connector is installed on the air outlet shroud and is electrically connected to the display screen. The second electrical connector is installed on the main frame and is electrically connected to the main control module. When the air outlet shroud and the main frame are connected, the second electrical connector and the first electrical connector are in contact with each other, so that the display screen and the main control module are electrically connected through the electrical connection mechanism. When the display screen is electrically connected to the main control module, it is used to display relevant data. The display screen mounted on the air vent is easy for users to view. The first electrical connector, installed on the air vent and electrically connected to the display screen, transmits signals to the screen. The second electrical connector, installed on the main frame and in contact with the first connector, ensures stable signal transmission between the two connectors. After the main control module is electrically connected to the second connector, it can achieve electrical conductivity with the display screen through both connectors. Because the display screen and main control module are electrically connected through the contact between the second and first connectors, separating the first and second connectors when the air vent needs to be removed avoids direct operation of the display screen and main control module, reducing the risk of damage during maintenance and replacement. When the air vent is reinstalled, the contact between the first and second connectors re-establishes the electrical connection between the main control module and the display screen. This achieves the technical effect of improving maintenance convenience and enhancing user experience. In addition, the display screen can also be used to display relevant data, so that in addition to the function of air supply and cooling, the fan head can also provide users with relevant prompts such as current temperature, current time, and current humidity based on the displayed data, making it a versatile device.

Figure 8 This is a schematic diagram of the structure of an air outlet cover in a fan head according to an embodiment of the present invention. Figure 9This is a schematic diagram illustrating the principle structure of the main control module in a fan head according to an embodiment of the present invention. The fan head provided in this embodiment includes a fan body 1, a display screen 2, and an electrical connection mechanism 3.

[0024] The two sides of the fan body 1 arranged opposite each other in the front-to-back direction are the air inlet side and the air outlet side, respectively. The air inlet side refers to the side of the fan body 1 where airflow flows in, and the air outlet side refers to the side of the fan body 1 where airflow flows out.

[0025] The fan body 1 includes an air inlet shroud 11, an air outlet shroud 12, and a main frame 13. The air inlet shroud 11 is located on the air inlet side, the air outlet shroud 12 is located on the air outlet side, and the main frame 13 is located between the air inlet shroud 11 and the air outlet shroud 12, and the main frame 13 is connected to both the air inlet shroud 11 and the air outlet shroud 12 (the air inlet shroud 11 and the air outlet shroud 12 are respectively connected to the main frame 13 on both sides in the front-to-back direction). The air outlet shroud 12 is detachably connected to the main frame 13; for example, the air outlet shroud 12 can be detachably connected to the main frame 13 by screws, by clips, by pins, or by magnetic attraction.

[0026] The display screen 2 is installed on the side of the air outlet cover 12 that is away from the air inlet cover 11.

[0027] The electrical connection mechanism 3 includes a first electrical connector 31 and a second electrical connector 32. The first electrical connector 31 is mounted on the air outlet cover 12 and is electrically connected to the display screen 2. The second electrical connector 32 is mounted on the main frame 13 and is used for electrical connection to the main control module 4. When the air outlet cover 12 and the main frame 13 are connected, the second electrical connector 32 contacts the first electrical connector 31, so that the display screen 2 and the main control module 4 are electrically connected through the electrical connection mechanism 3, and the display screen 2 can display relevant data when electrically connected to the main control module 4.

[0028] The first electrical connector 31 may include an electrical contact, and the second electrical connector 32 may include a metal spring that matches the electrical contact. When the metal spring and the electrical contact are in contact, electrical continuity is achieved. Alternatively, the first electrical connector 31 may include a metal spring, and the second electrical connector 32 may include an electrical contact that matches the metal spring. When the metal spring and the electrical contact are in contact, electrical continuity is achieved.

[0029] When the display screen 2 is electrically connected to the main control module 4, the display screen 2 is used to display relevant data to the user. The relevant data may include, but is not limited to, at least one of the following: current temperature, current humidity, current rotation speed, current date, and current time.

[0030] The main frame 13 provides support for the air inlet shroud 11 and the air outlet shroud 12. After the air inlet shroud 11 and the air outlet shroud 12 are firmly connected, the stability of the fan is improved. The main control module 4 is used to receive and process signals from various sensors, and can control the display content of the above-mentioned display screen 2 according to the preset program.

[0031] Based on the fan head in this embodiment, the air inlet shroud 11 and the air outlet shroud 12 are respectively connected to both sides of the main frame 13 in the fan body 1. The main frame 13 is located between the air inlet shroud 11 and the air outlet shroud 12. The air inlet shroud 11 is located on the air inlet side, and the air outlet shroud 12 is located on the air outlet side. The display screen 2 is installed on the side of the air outlet shroud 12 away from the air inlet shroud 11. In the electrical connection mechanism 3, the first electrical connector 31 is installed on the air outlet shroud 12 and is electrically connected to the display screen 2. The second electrical connector 32 is installed on the main frame 13 and is in contact with the first electrical connector 31. The main control module 4 is electrically connected to the second electrical connector 32. When the display screen 2 is electrically connected to the main control module 4, it is used to display relevant data. The display screen 2, mounted on the air vent 12, is easily accessible to the user. The first electrical connector 31, installed on the air vent 12 and electrically connected to the display screen 2, transmits signals to the display screen 2. The second electrical connector 32, installed on the main frame 13 and in contact with the first electrical connector 31, ensures stable signal transmission between them. After the main control module 4 is electrically connected to the second electrical connector 32, it can achieve electrical conduction with the display screen 2 through the first and second electrical connectors 31 and 32. Since the display screen 2 and the main control module 4 are electrically connected through the contact between the second electrical connector 32 and the first electrical connector 31 of the electrical connection mechanism 3, the separation of the first electrical connector 31 and the second electrical connector 32 when the air vent 12 needs to be disassembled avoids direct operation of the display screen 2 and the main control module 4, reducing the risk of damage during maintenance and replacement. When the air outlet cover 12 is reinstalled, the first electrical connector 31 and the second electrical connector 32 come into contact with each other, re-establishing the electrical connection between the main control module 4 and the display screen 2. This improves maintenance convenience and enhances the user experience. Furthermore, the display screen 2 can also display relevant data, allowing the fan head to provide users with various functions beyond just airflow and cooling, such as current temperature, current time, and current humidity.

[0032] As one implementation method, please refer to Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 9As shown, the first electrical connector 31 includes one of a conductive head 33 and a conductive base 34, and is electrically connected to the display screen 2. The second electrical connector 32 includes the other of a conductive head 33 and a conductive base 34, and is used to electrically connect to the main control module 4. The conductive head 33 is inserted into the conductive base 34. When the conductive head 33 is inserted into the conductive base 34, the conductive head 33 and the conductive base 34 come into contact with each other, making the first electrical connector 31 and the second electrical connector 32 electrically connected. Through the connection between the conductive head 33 and the conductive base 34, the electrical signal can be stably transmitted between the first electrical connector 31 and the second electrical connector 32. Alternatively, the above-mentioned electrical connection mechanism 3 may include a pogo pin, in which case the conductive head 33 may refer to the pin part of the pogo pin, and the conductive base 34 may refer to the socket part of the pogo pin. When the air outlet cover 12 needs to be disassembled, only the conductive head 33 and the conductive base 34 need to be separated, which can avoid direct operation of the display screen 2 and the main control module 4, reducing the risk of damage during maintenance and replacement. When the air outlet cover 12 is reinstalled, the re-insertion of the conductive head 33 and the conductive base 34 allows the electrical connection between the main control module 4 and the display screen 2 to be quickly restored, which helps to improve the convenience of maintenance.

[0033] In some implementations, please refer to Figure 2 , Figure 3 and Figure 9 As shown, there are multiple conductive heads 33, including a positive conductive head 32a, a negative conductive head 32b, and a functional conductive head 32c. There are also multiple conductive bases 34, including a positive conductive base 31a, a negative conductive base 31b, and a functional conductive base 31c. The positive conductive head 32a is inserted into the socket of the positive conductive base 31a, the negative conductive head 32b is inserted into the socket of the negative conductive base 31b, and the functional conductive head 32c is inserted into the socket of the functional conductive base 31c. The separation of the positive conductive head 32a, the negative conductive head 32b, and the functional conductive head 32c facilitates more complex circuit connections and functional expansion. At the same time, when the air outlet cover 12 needs to be disassembled or reinstalled, it is only necessary to operate the positive conductive head 32a, the negative conductive head 32b, and the functional conductive head 32c to insert them into the corresponding positive conductive base 31a, the negative conductive base 31b, and the functional conductive base 31c, respectively, so as to quickly establish or disconnect the electrical connection between the main control module 4 and the display screen 2.

[0034] It should be noted that when the display screen 2 is electrically connected to the main control module 4, it is used to display relevant data. This relevant data may include, but is not limited to, at least one of the following: current temperature, current humidity, current rotation speed, current date, and current time. For example, when the display screen 2 is electrically connected to the main control module 4 and is used to display the current temperature, the electrical signal output by the main control module 4 for displaying the current temperature is transmitted through the functional conductive base 31c and the functional conductive head 32c. Similarly, when the display screen 2 is electrically connected to the main control module 4 and is used to display the current humidity, the electrical signal output by the main control module 4 for displaying the current humidity is transmitted through the functional conductive base 31c and the functional conductive head 32c. Furthermore, when the display screen 2 is electrically connected to the main control module 4 and is used to display the current time, the electrical signal output by the main control module 4 for displaying the current time is transmitted through the functional conductive base 31c and the functional conductive head 32c. Of course, but not limited to time-division multiplexing, the functional conductive base 31c and the functional conductive head 32c can be used to transmit multiple electrical signals. In this case, the display screen 2 can display at least two relevant data such as current temperature, current humidity, current rotation speed, current date, and current time.

[0035] As one implementation method, please refer to Figure 3 As shown, the first electrical connector 31 also includes a first circuit board 311, which is mounted on the air outlet shroud 12. A positive conductive base 31a, a negative conductive base 31b, and a functional conductive base 31c are integrated on the first circuit board 311. The second electrical connector 32 also includes a second circuit board 321, which is mounted on the main frame 13. A positive conductive head 32a, a negative conductive head 32b, and a functional conductive head 32c are integrated on the second circuit board 321. The first circuit board 311 can include a PCB board or an FPC board, and the second circuit board 321 can also include a PCB board or an FPC board. The integration of the first circuit board 311 and the second circuit board 321 makes the electrical connection mechanism 3 more compact and efficient. The conductive bases 34 and conductive heads 33 on the corresponding circuit boards can be positioned and connected more precisely, which is beneficial to improving the stability and reliability of electrical signal transmission.

[0036] In some implementations, please refer to [link / reference]. Figure 3 As shown, the fan head also includes a baffle 5, which is mounted on the air outlet cover 12. The baffle 5 has a first through hole 51, a second through hole 52, and a third through hole 53 spaced apart. The positive electrode conductive seat 31a is embedded in the first through hole 51, the negative electrode conductive seat 31b is embedded in the second through hole 52, and the functional conductive seat 31c is embedded in the third through hole 53. The baffle 5 helps protect the conductive seat 34 from external interference and damage, improving the durability of the electrical connection mechanism 3. At the same time, the through holes on the baffle 5 also ensure the precise alignment and stable connection between the conductive seat 34 and the conductive head 33.

[0037] As one implementation method, please refer to Figure 2 , Figure 6 , Figure 8 and Figure 9 As shown, the main frame 13 has a wiring cavity 131, and the electrical connection mechanism 3 further includes a first wire harness. The first wire harness is arranged inside the wiring cavity 131, with one end of the first wire harness electrically connected to the second electrical connector 32 and the other end of the first wire harness electrically connected to the main control module 4. The arrangement of the first wire harness within the wiring cavity 131 avoids exposed and messy wires, improving the overall aesthetics and safety of the fan head. Simultaneously, the stable connection between the first wire harness, the second electrical connector 32, and the main control module 4 ensures reliable transmission of electrical signals.

[0038] As one implementation method, please refer to Figure 2 As shown, the main frame 13 includes an inner frame 132 and an outer frame 133. The air inlet shroud 11 and the air outlet shroud 12 are respectively connected to both sides of the inner frame 132, and / or the air inlet shroud 11 and the air outlet shroud 12 are respectively connected to the outer frame 133. The inner wall of the outer frame 133 and the outer wall of the inner frame 132 enclose each other to form a wiring cavity 131. For example, at least a portion of the inner wall of the outer frame 133 may be spaced from the outer wall of the inner frame 132 to form the wiring cavity 131, or the inner wall of the outer frame 133 may be recessed to form the wiring cavity 131, or the outer wall of the inner frame 132 may be recessed to form the wiring cavity 131. The wiring cavity 131 formed between the inner frame 132 and the outer frame 133 of the main frame 13 provides a neat and orderly space for the wiring harness of the electrical connection mechanism 3, which not only avoids exposed and messy wires but also improves the overall aesthetics and safety of the fan head, and helps protect the wiring harness from external interference and damage. Meanwhile, the wiring cavity 131 also facilitates the maintenance and replacement of the wiring harness, improving the convenience of maintenance.

[0039] In some implementations, please refer to Figure 8As shown, the air outlet cover 12 includes a connecting shell 121, an air outlet frame 123, and multiple air outlet baffles 124. The multiple air outlet baffles 124 are respectively connected to the connecting shell 121 and the air outlet frame 123, and are located between the connecting shell 121 and the air outlet frame 123. The display screen 2 is installed on the side of the connecting shell 121 opposite to the air inlet cover 11. The first electrical connector 31 is installed on the air outlet frame 123. The air outlet frame 123 is detachably connected to the main frame 13, allowing users to install or replace the air outlet cover 12 without complicated operations, thus improving installation efficiency. During maintenance, users only need to disassemble the air outlet frame 123 to inspect or replace the display screen 2 or the first electrical connector 31, without disassembling the entire fan head, thus improving maintenance convenience. Simultaneously, the first electrical connector 31 is integrated into the air outlet frame 123, making the electrical connection between the first electrical connector 31 and the display screen 2 more stable. When the air outlet cover 12 is connected to the main frame 13, the first electrical connector 31 and the second electrical connector 32 are in close contact, achieving stable transmission of electrical signals and improving the stability of normal display of the display screen 2. The electrical connection mechanism 3 also includes a second wiring harness (not shown in the figure). One end of the second wiring harness is electrically connected to the first electrical connector 31, and the other end of the second wiring harness is electrically connected to the display screen 2. As one embodiment, the interior of the air outlet baffle 124 near the position of the first electrical connector 31 is hollow to form a receiving cavity. The second wiring harness is entirely located in the receiving cavity, and both ends of the hollow air outlet baffle 124 are respectively connected to the air outlet frame 123 and the support housing 1211, so that the second wiring harness can pass through the hollow air outlet baffle 124 to achieve the electrical connection between the first electrical connector 31 and the display screen 2. It should be noted that the second wire harness can also be partially located in the receiving cavity of the air outlet baffle 124. In this case, the air outlet baffle 124 has a through hole on the side near the air outlet frame 123, and another through hole on the side near the support housing 1211. One end of the second wire harness passes through the through hole and is electrically connected to the first electrical connector 31, and the other end of the second wire harness passes through the other through hole and is electrically connected to the display screen 2.

[0040] As one implementation method, please continue to see Figure 8As shown, the connecting shell 121 includes a supporting shell 1211 and a protective cover 1212. The protective cover 1212 is detachably connected to the supporting shell 1211. For example, corresponding screw holes are reserved on the protective cover 1212 and the supporting shell 1211, and the protective cover 1212 and the supporting shell 1211 are fixed to each other by screws. Alternatively, magnetic elements are installed on the protective cover 1212 and the supporting shell 1211, and the protective cover 1212 and the supporting shell 1211 are fixed to each other by magnetic force. Or, a pin is provided on the protective cover 1212, and a slot corresponding to the pin is provided on the supporting shell 1211, and the protective cover 1212 and the supporting shell 1211 are fixed to each other by inserting the pin into the slot. The support housing 1211 is connected to multiple air outlet panels 124. The support housing 1211 and the protective cover 1212 enclose a receiving space 122 for placing the display screen 2. The receiving space 122 has space inside for placing the display screen 2. The display screen 2 can be installed inside the receiving space 122 by screws or adhesive. The protective cover 1212 can be made of a highly transparent material, allowing the user to view the display screen 2 from the outside of the receiving space 122. By connecting the support housing 1211 and the protective cover 1212, the replacement and maintenance of the display screen 2 becomes more convenient for the user. For example, the user only needs to remove the protective cover 1212 to inspect or replace the display screen 2 without disassembling the entire air outlet cover. Meanwhile, the protective cover 1212 effectively prevents dust and moisture from entering the containment space, protecting the safety and normal operation of the display screen 2. The protective cover 1212 can also be used to fix the display screen 2, preventing it from shifting or being damaged during operation.

[0042] The desktop fan includes a base 6, a support structure 7, the aforementioned fan head, and the aforementioned main control module 4. One end of the support structure 7 is connected to the base 6, and the air inlet shroud 11 is connected to the other end of the support structure 7. The main control module 4 is located inside the base 6. The support structure 7 has a wiring channel for the first wire harness to pass through.
